SHUTTLE FOR WEAVERS LOOMS.

SPECIFICATION forming part of Letters Patent bld-728,694, dated May 19,1903. Applicashun@ July 26,1902. seria No. 117,161. in@ modem To @ZZwhom. it may concern: Y

Be it known that I, EDUARDO GoMEs FER- REIRA, manufacturer, a citizen ofthe Republic of Brazil, residing at 83A Rua Primeiro de Marco, RioJaneiro, Brazil, have invented certain new and useful Improvements inShuttles for Weavers Looms, of which the following is a specification. I

This invention relates to certain new and useful improvements in weaversshuttles; and the object thereof is to provide a shuttle with a deviceto assist in rapidly passing the bobbin-thread through the eye of theshuttle, thereby overcoming the objection to suction generally employedfor this purpose.

The invention further aims to construct the said device in such a mannerthat it will cause the bobbin-thread after unwinding to pass in anoblique manner toward the eye of the shuttle.

'Ihe invention further aims to construct a weavers shuttle provided witha device, as set forth, which shall be simple in construction, strong,adapted to reinforce the head of the shuttle, durable, efficient in itsuse, and comparatively inexpensive to manufacture.

\Vith the above and other objects in view the invention consists of thenovel combination and arrangement of parts hereinafter more specitically described, illustrated in the accompanying drawings, and particularlypointed out in the claims hereunto appended.

In describing the invention in detail reference is had to theaccompanying drawings, forming a part of this specification, whereinlike reference characters denote corresponding parts throughout theseveral views, and in which- Figure l is a sectional elevation of ashuttle provided with my improved threading and thread-directing device.Fig. 2 is a plan of a shuttle with my improved device attached thereto.of the shuttle, showing my improved device in dotted lines. Fig. 4: is asection on the line a Z2 of Fig. 1. Fig. 5 is afront view, Fig. 6 is atop plan view, Fig. 7 is side elevation, and Fig. 8 is a rear elevation,of the threading device; and Figs. 9 and 10 are a side and a top plan,respectively, of the socket adapted to be mounted in the eye-bore.

Referring to the drawings by reference Fig. 3 is a side elevation of theheadl characters, the head of the shuttle is provided with a recess 1,having an open top a, and which is a continuation in a longitudinaldirection of the opening B in the shuttle for the bobbin C. The bobbin Cis mounted upon the spindle E. The shuttle-head is provided with anoblique bore 2, terminating at its inner end in the recess 1 and at itsouter vend in a shuttle-eye D. The bore 2 will be termed the eye-bore.

Vithin the recess 1 is secured, by means of the rivets 4 or othersuitable fastening means, the threading and thread-directing device A,which is constructed of a pair of side walls 3 32, thev bottom wall 3',and a forward or main wall 5. The bottom wall 3 is preferablycurvilinear in contour and is or may be formed integral with the sidewalls 3 32 and is further constructed in such a manner that its forwardedge or end extends in an oblique manner. The side wall 32 is of agreater length than the side wall 3', and the walls 3 3 32 are or may beformed integral with the forward or main wall4 5. From the constructionof the threading and thread-directing device it will be evident that theforward or main wall 5 will extend obliquely of the recess 1. Theforward or main wall 5 is provided with an orifice 55,whichV is providedwith'a slit t, which extends upwardly in an oblique manner from theorifice 6 to the corner formed by the juncture of the walls 32 5. Theslit t permits of the introduction of the thread o to the threadingdevice A. The introduction of the thread o to the threading anddirecting device A is assisted by providing the end of the slit t withan enlarged mouth 9, formed by the rounding off of the wall 32 at anangle to the top edge 10 of the wall 32 toward the edge 8 and therounding o of the wall 5, as at 11.

' The lateral Wallof the recess l on the side of the eye D is providedwith a vertical or slightly-inclined slit 12 and which extends from thetop of the wall of the recess to the bore 2.

Y may be made in the details of constructionv The eye-bore 2 may beprovided With a slitted eyelet or metallic socket F with ixinglugs 13,and the slit therein is indicated at 12', corresponding to the slit 12in the wall of the recess 1.

From the foregoing it will be evident that to introduce the thread ointo the orifice 6 and bore 2 the thread is grasped and passed to theorifice 6 through the slit t, the mouth 9 of the slit t facilitating thepassage of the thread. The thread o is then placed in the slit 12 andfinally pulled downward into the eye-bore 2, With its free end outsidethe shuttle. It will also be evident that the threading device willreinforce the head of the shuttle, owing to the fact that it isconnected, by means of the rivets 4, thereto. It will also be evidentthat owing to the obliquely-extending wall 5 of the threading and threaddirecting device the vthread will be directed obliquely toward the eyeof the shuttle.

It is thought the many advantages of my improved shuttle can be readilyunderstood from the foregoing construction, taken in connection with theaccompanying drawings, and it will also be evident that minor changesWithout departing from the general spirit of my invention. y

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

1. In combination with a shuttle provided with an eye, of a threadingand thread-directing device mounted therein and consisting of a pair ofsidewalls, a bottom and a main wall, said main wall extending obliquelyand provided with an orifice and an obliquely extending slit terminatingat its lower end in said orifice.

2. A threading and thread-directing device for shuttles comprising apair of side walls, one ot which is of greater length than the other, abottom wall connected therewith and a main wall extending in an obliquemanner and connected to the said side and bottom walls, said main Wallprovided with an orifice, and a slit terminating at its lower end insaid orifice, said slit extending in an oblique manner and provided withan enlarged mouth..

3. A threading and thread-directin g device for shuttles comprising apair of side walls, one of which is of greater length than the other, abottom wall connected therewith and a main Wall extending in an obliquemanner and connected to the said side and bottom walls, said main Wallprovided with an oritice and a slit terminating at its lower end in saidorifice, said slit extending in an oblique manner.

4. In combination, a shuttle provided with a recess and an eye-boreextending in an oblique manner, said shuttle further provided with aslit terminating in said bore, a thread.

ing and thread-directing device mounted in said recess and provided witha main Wall extending in the sam-e direction as the said bore, said mainWall further provided with an orifice and an obliquely-extending slitter- .minating in said orifice.

5. In combination, a shuttle provided with a recess and an eye-boreextending in an oblique manner, said shuttle further provided With aslit terminating in said bore, a threading and thread-directing devicemounted in said recess and provided with a main wall extending in thesame direction as the said bore, said main wall further provided with anorifice and an obliquely-extending slit terminating in said orice, saidslit having an enlarged mouth.

In testimony whereof I have hereunto set my hand in presence ot' twosubscribing witmesses.
